A city assessor’s laptop uses EAP-TLS on the staff SSID. Authentication started failing on the same day the user’s certificate expired according to the help-desk ticket. What is the best technician conclusion?
Select an answer to reveal the explanation.
Short Explanation
EAP-TLS is certificate auth—when the user cert ages out, the EAP exchange fails. Treat the expired cert as the security fault, renew or re-enroll, and retry. Don’t chase PoE or pretend EAP-TLS is a PSK network.
Full Explanation
EAP-TLS relies on valid certificates for client (and often server) authentication. Expiration, revocation, or trust-chain problems present as EAP authentication failures on Enterprise WLANs. Channel width and PoE status are separate physical/RF or power issues and do not explain certificate-timed EAP-TLS failure. Technicians renew or replace the client certificate per organizational process and retest association.
